Transmission issues, Please help

I have a question about my 2003 BMW 745LI, with 90k miles on it. I recently got the mechatronics sleeve replaced along with the pan, bottom gasket and filter. I bought three quarts of tranny oil from BMW my self and brought it to the mechanic. I got a transmission fail safe mode error and noticed there was a leak this is what triggered the transmission service. The car had the transmission fail safe error however was shifting fine before the service.



I want to emphasize that before the car went into the shop it would shift a little hard into first every once and a while. All other gears shifted smooth and perfectly. I picked the car up yesterday from the transmission service and I noticed a distinct difference immediately. The car is shifting hard into every gear, as if it was a manual transmission. I have noticed that the RPM are also fluttering when coasting. It shift really hard coming to a stop from 4th to 3rd and 3rd to second. If stopping abruptly it slams into first gear from 3rd, it feels like as if I was getting rear ended. Right before I got home coming out of a complete stop it reved up and then slammed into first gear. I don't understand how the car drove for the most part perfectly before the service and now so terrible after the service. Please help

Try resetting the transmission adaptation values in INPA. You need to find the source of the leak too. When my car RPM's fluttered at a coast BMW replaced my transmission under warranty.

Well the leak was coming from the mechatronics sleeve, that is what was replaced at the mechanic leading to these problems. The car drove fine, did the sleeve, pan, gasket, and filter now it is slipping and banging into almost every gear.

You forgot about mechatronik adapter which is more important than anything else in this tranny service

Can you please elaborate on what you mean by this? I haven't read anything that suggests that the adapter should be change because of a seal leak>

Probably. That extra L in Wilson did not do the search any favors.
